那仁郭勒河流域地表水与地下水储量变化响应研究

基于2001—2016年的地表水和地下水储量数据,分别从年尺度和季节尺度研究那仁郭勒河流域地表水与地下水资源变化趋势,分析地表水与地下水的响应关系及其影响因素.结果表明,那仁郭勒河流域地表水储量和地下水储量变化趋势分布不均匀,季节差异明显.地表水-地下水储量变化响应在流域北部集中呈现"地表水稳定-地下水减少"的趋势,在...

Changes of Surface and Groundwater Reserves in the Narenguole River Basin

Based on the data from 2001–2016, we investigated the variation trends in surface water and groundwater reserves of the Narenguole River, their response relationship and influencing factors. The trend distribution of groundwater reserves is uneven and the seasonal variation is obvious. The co-varying change of surface water and groundwater reserves presents a “stable-decrease” trend in the northern part of the basin. In the part of the Tulagt Ar Gol River, the surface water decreases but the groundwater increases, while the “stableincrease” and the “decrease-decrease” co-varying trends are observed respectively in the West and East Taijinar Lakes of the rump area. The main factors influencing the change of water reserve include temperature, soil section thickness, irrigation factors and population factors. Based on the response characteristics of surface water and groundwater changes in different areas of the basin, we get insights into the typical non-consistent response relationship between them, which is very helpful to realize the integrated management of surface water and groundwater and the protection of ecological environment in the basin.
